Song Sung Gyu, later legally changed to Song Chang Gyu, is a South Korean singer, dancer, and member of UNVS (유니버스; previously known as UNIVERSE 世界少年).

In late 2014, he was set to debut as part of 5-member group F-ACE (페이스; stylized as F★ACE) under the stage name Changgu Ear. However, HEM Freedom Entertainment kept delaying its debut and faced some financial difficulties. As a result, 4 members decided to leave the agency, and the group never debuted.

After switching agencies, he made his debut in December 2016 as UNIVERSE's lead vocalist with their first digital single, "I'll Be There" (sung in Mandarin). The group became the first South Korean idols to officially debut in Taiwan instead of their own country. Their agency, CHITWN Music (샤이타운뮤직), originally wanted them to return to training and prepare for their South Korean debut in early 2019. However, this was delayed when 3 of the original 5 members left the agency and were replaced without any explanation.

He finally debuted in South Korea in February 2020 with the digital single, "Timeless". Unfortunately, they did not release any new material afterwards, and while they have not officially disbanded, they have remained on an indefinite hiatus since 2022.

He enlisted for his mandatory military service on November 16, 2020 and was discharged on May 15, 2022. Then, in April 2025, he announced his marriage to singer Hwang Ah Young.
